So you know that 15-second Harry Potter and the Half-Blood Prince teaser that's playing before The Dark Knight? Yeah, well it's just hit The Tube ... and you can see it above. Unfortunately, it's very much a teaser in that there's no actual footage from the film at all. All we hear is Dumbledore's voice saying, "Once again, I must ask too much of you Harry." Then there's some lights, and -- ta da -- we get the title: Harry Potter and the Half-Blood Prince. Following the title, there's this: Select Sequences in IMAX 3-D. Yeah, I'm thinking that will look pretty damn cool. I wish we had more to give you Potter nuts right now (you can also check out our nifty gallery below), but this is all there is. However, a little wizard told me there might be some more gifts arriving soon ...

Harry Potter and the Half-Blood Prince hits theaters on November 21.
